Thread: 12-803 Fuel Pressure Regulator Issues

    Default 12-803 Fuel Pressure Regulator Issues

    I'm using a Holley Blue pump & the regulator to supply fuel for my NOS system.

    The regulator is good for 4.5-9 psi, according to Holley. I'm looking for 5.5 psi.
    When I went to set this up at 9 psi, the regulator was fine, but when I dropped it to 5.5, the needle
    on my setup gauge was bouncing and unsteady and you could here the regulator making a noise.

    I left it as is, but it was still a concern.

    The pump/regulator have never been used until this weekend.

    Any ideas on what to do to fix this fluctuating issue? Thanks.
